摘　　要：本文给出一种分形微带天线在天线雷达散射截面 (RCS)减缩中应用的示例 .分形结构具有独特的空间填充性能 ,利用该性能可以探索分形天线在天线RCS减缩中的应用 .设计出的分形天线与常规天线的辐射性能进行了比较 ,可以看出分形天线基本保持了原辐射性能 .同时比较了两者的散射性能 ,可以看出分形天线有一定的RCS减缩效果 .本文的内容对天线隐身有一定的借鉴作用 .A fractal microstrip patch antenna is illustrated for antenna Radar Cross Section (RCS) reduction. Fractal structure has the special ability of space filling which can be explored for antenna RCS reduction. The characters of the designed fractal microstrip patch antenna are compared with those of traditional patch antenna. The results show that fractal antenna retains the radiation character and also has RCS reduction to some extent, which is helpful to the antenna RCS reduction.
